Foundation Crack Repair Detroit MI
A crack in your foundation is not just cosmetic — it is water’s entry point and a warning sign of structural movement. 313 Foundation Fix uses epoxy and polyurethane injection to permanently seal cracks in poured concrete walls and block foundations throughout Metro Detroit.
Types of Foundation Cracks We Repair
- Vertical cracks — Most common in poured concrete walls, typically caused by concrete curing shrinkage or minor settlement. Sealed with epoxy injection.
- Horizontal cracks — The most serious type. Indicate soil pressure bowing your wall inward. Require wall stabilization in addition to crack repair.
- Stair-step cracks — Found in block or brick foundations. Follow mortar joints in a stair pattern. Indicate differential settlement.
- Diagonal cracks — Often found at corners of windows and doors. Can indicate foundation settlement or movement.
Our Crack Repair Process
We begin with a visual inspection and moisture assessment. Active water leaks are addressed first with hydraulic cement before injection. Once the crack is dry, we drill injection ports at 8–12 inch intervals along the crack. Low-pressure epoxy or polyurethane resin is injected from the bottom port upward until the entire crack is filled. Ports are removed and patched. The result is a bond stronger than the surrounding concrete.
Epoxy vs. Polyurethane: Which Do We Use?
Epoxy injection is rigid and creates a structural bond — best for dry cracks where structural strength is the priority. Polyurethane foam is flexible and expands to fill voids — best for wet, actively leaking cracks. We assess each crack and use the right material for the situation.
Frequently Asked Questions
How much does crack repair cost in Detroit?
Most crack injections run $400–$800 per crack depending on length, depth, and accessibility. We provide written quotes before starting work.
Do repaired cracks come back?
Properly injected cracks do not re-crack at the same location. However, if the underlying cause — settlement, soil pressure, or drainage — is not addressed, new cracks can form nearby. We assess root causes during every inspection.
